HYMAN HATCH AND ALBERT T. HATCH, OF SOUTH ELGlN, ILLINOIS.

WHlF'FL-ETREE-HOOK.

SPECIFICATION forming part of Letters Patent No. 271,632, dated February6, 1883.

Application filed November 6, 1882. (ModeL) To all whom it may concern:

Be it known that we, HYMArI HATCH and ALBERT T. HATCH, both of SouthElgin, in the county of Kane and State of Illinois, have inventedcertain new and useful Improvements in Whiffletree-Hooks; and we dohereby declare that the following is a full, clear, and exactdescription of the invention, which will enable others skilled in theart to which it appertains to make and use the same, reference being badto the accompanying drawings, and to letters of reference markedthereon, which form a part of this specification.

The object of this invention is to furnish a whiffletrce-hook of greatstrength, simple in construction, devoid of all springs and lookingappliances, bolts, or nuts,'which could get loose or out of order, andwhich cannot under any conditions let the trace become accidentallydetached from it; and its construction and advantages will readilyappear from the following description.

Figure l is a perspective view of our improved device, the book being inthe position it occupies when in use with the trace connected to it;Fig. 2, a plan of the device applied to one end of a whi'lfletree, andshowing the swinging hook swung out to the proper position forconnecting or disconnecting the trace; Fig. 3, a top view; Fig. 4, abottom view, and Fig. 5 an end view.

A is a metallic sleeve or cap, having at its back and integral therewitha grooved rib or bed, I), and two lugs or ears, 0 c, and having alsointegral with it on the side opposite these lugs an arched groove, (Z,between .two ribs, 6 c. This sleeve or band A should preferably be madeintegral, with an arched, tapering, or conical end, a, and this end willthen cover, house, and protect the end of the whiffletree, and thecurvature or are of the front a oft-his end a should, in conjunctionwith the arch of groove cl, constitute substantially an arc of a circledescribed from the axis of the swinging hook F. It the sleeve be madewithout this end a, then the whiffletree should project through thesleeve and have its end shaped substantially like such end a.

F is the hook, composed of ajournaled yoke,

g, terminating in a hooked end, h. It is made of a single piece or barof iron, and one end being first put through the holes orjournalbearings'52, made in the ears 0 c, the shorter end is forged or bent up intoclose contact with the other end, thus closing the yoke part of thehook. The entire hook F is thus free to be swung in its bearings z i,and itsjournal portionj lies in the groove k of the bed or rib b. Thetip of the hooked end h curves inward toward the yoke g, as shown, andthis tip comes in very close proximity to the whole of the above-namedarc of the sleeve when swung around it, and when the hook is in positionfor the pull of the traces the tip is within the groove d, and remainswithin it during any sweep or range of its motion of, say, sixtydcgrecs.

To attach a trace to or to detach it from the hook, it will be seen thatthe book must be swung out about ninety degrees (90 or more before spaceenough is given between the tip of the hook and the outer extremityot'the tree or cap to release or to hook on the trace, and that when thetip is in the groove the hooked end h is practically a closed one, andthat the direction of the strain or draft tends always to preserve thiscondition, and the bend of the tip turns or curves inward and into thisgroove when the hook has reached the limit of its inward movement.Should the book, by any accident, he swung out of'the groove, or even tothe position shown in Fig. 2, it would not be easy for the trace tobecome detached from it, because the tip curves so far toward theconverging or narrow part of the yoke.

The lugs 00 and their connecting-rib I) give great strength to thestructure, and, being at the back of the whiffietree, receive anddistribute all the strain of the draft, so that even if there were aweaker defective place in the sleeve orlugs the pull or strain wouldnottend to increase, but, on the contrary, to counteract it. A singlescrew will serve to hold the sleeve or cap to the whiffletree.

o claim-- 1. The sleeve or cap A, as made with the lugs c c at its backand with the ribs 0 e at its front, in combination with the swingingwith the swinging hook F g h, applied thereto hook,jonrn a1ed in theselugs, and arranged to and operating therewith as set forth. have its tipride in the groove between the HYMAN HATCH. ribs, as and for thepurposes set forth.
